* cmListFileLexer: Do not require files to be seekableSergiu Deitsch2025-09-192-48/+162
| | | | | | Read the BOM sequentially and store the read bytes for later use if these do not correspond to a BOM. This allows FIFO to be used as input, e.g., for piping input or Bash process substitution.

* Source: Remove unused cmCommandArgument{Lexer,Parser}Brad King2025-01-206-5216/+0
| | | | | These were used only for the CMP0053 OLD behavior, which has now been removed.
* cmake_transform_depfile: Handle escaped colons in depfile contentPhilipp Borsutzki2024-04-302-42/+54
| | | | | | | Support escaped colons in windows paths containing driver letters (e.g. `c\:\\`) when parsing depfiles. Fixes: #25943
* Source: Fix mysterious new IWYU warningsKyle Edwards2023-08-292-0/+8
|
* IWYU: Update for Debian 12 CI jobBrad King2023-07-288-846/+838
| | | | | | `include-what-you-use` diagnostics, in practice, are specific to the environment's compiler and standard library. Update includes to satisfy IWYU for our CI job under Debian 12.
* Fortran: Teach lexer to recognize LLVMFlang preprocessor dependenciesBrad King2023-05-092-69/+74
| | | | | The line directives have the form `#line <path> <number>`, and do not have the line number before the path as other compilers do.
* Fortran: Restore support for parsing "end interface X"Brad King2022-11-302-146/+161
| | | | | | | | | Since commit 219a9b1e14 (Fortran: Fix suprious dependencies with submodules, 2022-07-30, v3.25.0-rc1~327^2) we accidentally fail to recognize `end interface X`, causing all subsequent modules to be seen as an interface. Fixes: #24203
* Fortran: Fix suprious dependencies with submodulesVitaly Mogulian2022-08-092-191/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit 695f0d0d3a (cmFortranParser: Parse keywords as lexical tokens, 2016-09-05, v3.7.0-rc1~150^2) we created keyword-specific variants of the original `USE WORD other EOSTMT` production, such as `MODULE WORD other EOSTMT` and `INTERFACE WORD other EOSTMT`. The same pattern was used by more keyword-specific productions in commit b5ac8b8aa7 (Fortran: Add support for submodule syntax in dependency scanning, 2016-09-05, v3.7.0-rc1~73^2~1). The postfix part (`other`) of several keyword-specific productions is not needed to match Fortran syntax. See the Fortran 2018 standard, para.4.1.4/1 on p.28, para.14.2.1/2 on pp.293-294. The postfix is needed only for a case of operator 'use': use <module-name> [, only : <list-of-vars>] The unnecessary postfix matching from the keyword-specific productions such as module, submodule, and interface declarations can cause spurious module dependencies to be detected, so remove it. Extend the test suite with examples covering the previously-broken cases. Fixes: #18427
* Fortran: Teach lexer to handle CRLF newlinesBrad King2022-08-092-192/+201
| | | | | | | We read sources in binary format, so we need to explicitly match CR (`\r`) characters that occur as part of newlines in CRLF sources. This is particularly important when line continuation (`&`) occurs in the middle of module declaration or usage.

* LexerParser: Regenerate parser files with GNU Bison 3.7.4Christoph Grüninger2021-01-258-3658/+3969
| | | | Adjust expected test output.
* LexerParser: Manual removing code from Bison is no longer neededChristoph Grüninger2021-01-254-11/+0
| | | | | This was needed to avoid warnings while compiling the sources generated by older versions of GNU Bison, but is not with GNU Bison 3.7.4.
* LexerParser: Do not use GNU Bison's yacc mode, we use Bison extensionsChristoph Grüninger2021-01-254-4/+4
| | | | Silence Bison warnings regarding use of Bison extensions.
* cmGccDepfileReader: Rework helper codeKyle Edwards2020-10-132-2/+2
| | | | | Fix some of the semantics of the depfile, add error handling, and refactor cmGccDepfileLexerHelper.
* cmCommandArgumentParserHelper: rework input handlingOleksandr Koval2020-09-092-19/+10
| | | | | | | | Old implementation uses involved Flex input management technique that requires usage of obsolete YY_INPUT macro. This causes a lot of useless allocations and byte-by-byte scanning. New implementation avoids those hacks, it uses yy_scan_string() API to setup Flex input. Also it fixes reporting of syntax error position and corresponding tests.
* cmake_command: Add command to EVAL a CMake script as a stringCristian Adam2020-03-032-22/+6

* Add a parser for GCC-style depfilesJoerg Bornemann2020-01-284-0/+2971
| | | | | | | | | | | Introduce the function cmReadGccDepfile that parses a GCC-style depfile and returns its content. The implementation uses a lexer that is modeled after the re2c implementation in Ninja. The sample files of the autotest have been created with gcc 8.3.0. This depfile reader is to be used by the Autogen facility to make use of the depfiles that are generated by Qt's meta object compiler.

* cmListFileLexer: Add missing include to avoid possible pointer truncationZsolt Parragi2019-02-132-2/+2
| | | | | | | The `cmsys/Enconding.h` include had a typo in its surrounding ifdef, possibly causing a missing function declaration (`cmsysEncoding_DupToWide`). As this is C code, this resulted in the code compiling, but with a truncated return value, possibly causing crashes.
* Fix most clang -Wextra-semi-stmt warnings in C++ filesSean McBride2019-01-1512-12/+12
| | | | Suppress one in code generated by flex.
* Source/LexerParser: Suppress "Use of zero-allocated memory" warningKyle Edwards2019-01-148-0/+40
| | | | | | | clang scan-build warns about YY_CURRENT_BUFFER_LVALUE being zero- allocated, but the whole point of the macro is to know that it's not zero. Wrap the entire file in an "#ifndef __clang_analyzer__" block in order to suppress the warning.
* Fortran: Fix module dependency scanning with upper-case SUBMODULEBrad King2018-11-202-114/+114
| | | | | | | | The lexical token expression added by commit v3.7.0-rc1~73^2~1 (Fortran: Add support for submodule syntax in dependency scanning, 2016-09-05) has a typo and does not match upper-case `B` in `SUBMODULE`. Fix it. Fixes: #18595
* LexerParser: Suppress GCC -Wconversion warningsBrad King2018-07-319-880/+904
| | | | | GCC 8 warns about some of the conversions in bison-generated code. Suppress the warnings.
* math: Restore toleration of unexpected characters in an expressionBrad King2018-07-165-73/+67
| | | | | | | | Prior to commit 7c4c13ffef (math: Reject unexpected expression input explicitly, 2018-05-18) we ignored unexpected characters in an expression that otherwise can be parsed. In order to preserve compatibility with projects that accidentally used this, convert the error to a warning.

* | ListFileLexer: Do not match null bytes in inputBrad King2018-06-262-103/+99
|/ | | | | | | | | | | Extend the fix from commit v3.10.0-rc1~188^2 (ListFileLexer: fix heap-buffer-overflow on malicious input, 2017-08-26) to apply to all lexer token matches. Replace all `.` with `[^\0\n]`. Update all `[^...]` match expressions to not match `\0`. We cannot safely process null bytes in strings. Fixes: #18124
* Fortran: Add support for submodule dependenciesBrad King2018-04-202-4/+4
| | | | | | | | | | | | | | | | | | | | | Since commit v3.7.0-rc1~73^2~1 (Fortran: Add support for submodule syntax in dependency scanning, 2016-09-05) we support parsing Fortran sources that use submodule syntax, but it left addition of `.smod` dependencies to future work. Add it now. The syntax submodule (module_name) submodule_name means the current source requires `module_name.mod` and provides `module_name@submodule_name.smod`. The syntax submodule (module_name:submodule_name) nested_submodule_name means the current source requires `module_name@submodule_name.smod` provides `module_name@nested_submodule_name.smod`. Fixes: #17017
